How is "sexting" really any different than telling someone over the phone, or in person? I don't get the moral panicking about that at all. I think part of is that it's young people exploring their sexuality ("what? young people aren't just holding hands and watch rom coms?") in ways older people haven't, and that obviously must be bad, because sex, right?
The thing people SHOULD be crying out about is how some idiots spread the material they've received, instead of putting the blame on an entirely healthy practice of turning each other on.
